. To all whom may concern:

Be it known t hat l, PAUL it. Waennii, a

citizen of the United States, residing at Jersey City, in the county oft Hudson and 5 tdtate of New Jersey, have invented a certain new and useful .lmprovement in Dyeing Machines, of which the following is a speciiication.

The invention relates to mechanism for supporting the material to be. dyed, present ing it to the dyeing liquor, and removing it therefrom, and 1S intended especially tor treating yarns and the like in skeins.

The main ob ect oi the invention is to pro-- vide a powerdriven machine adapted to serve. with a multiplicity of skein-carriers and the usual dye tank, and perform the (l sin o oerations in a manner closel I anal- .l i k: d

ing larc'e quant cally, expeditiously and efliciently with but ogous to hand dyeing, and capable of treat ities or material economilittle labor and in relatively small space.

Another impo means whereby the loaded skein-carriers may be grouped in close relation to each other 111 the tank, or transferred and. accumulated rtant object is to provide idly above the-tankfor removal or for permitting the dye to be acted upon by the air as in the oxidizing processes, or for permitting free access to the tank.

A further object is to provide simple,

automatically operated means whereby the carriers may be turned to present new per-- tions of the skeins to the action of the liquor, and another important object is to provide means for automatically removing excess skelns during the passage liquor from the of the carriers from the tank.

, The invention consistsm certaln novel teatures of constru ction and arrangement by which the above and other objects are at tained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification andshow an apparatus capable of carrylng outthe invention.

The tank 1.0 containing the dye liquor may be the usual rectangular vat used in the common hand dyeing processes with the top edges oi? its sides adapted to support the skein-carriers, and. on each side oi? the tank arevertical standards 1.1 carrying the mechanism by which the skeins are introduced to and. removed from the liquor.

The standards at one end of the tank are taller than those at. the other and are joined above by an inclined beam 12 well outside the tank on one side thereof, and a beam 13 similarly located on the other side. Joined to the beams by horizontal braces 16 are rails 14 and 35 parallel with but shorter than the beams. In plan view the rails lie close in line with the side-walls of the tank, and like the latter are adapted to support the skein-carriers.

Below the beams 12 and 13, at each end and in line therewith, are short horizontally disposed bars 17 and 18 supported by the standards at a level a little above the tank.

The standards, beams, rails, and bars, with certain additional parts, constitute the frame of the machine and are independent of the tank.

@n tl e outer face of the beam 12 is a main shaft 19 slidably mounted in hearing; brack ets 20 and arra ed to be moved axially by a shittingdevcr 2i. controlling a shiftingmechanism 22 only partially shown. Fixed on the shaiit near its ends are niitre pinions 23 and 9.4:; one, marked 23. adapted to mesh. with a mitre gearwheel 25 on a transverse shaft 527 at one end of and above the tank, supported in bearings 28 on the under faces of the beams, a similar shaft 26 is mounted in bearings 28 at the other end oi the beams but carries no mitre gear-wheel. The lower endot the inclined main shaft 19 carries a spur gearwheel 29 in mesh with a long pinwith such gearwheels.

ion on the shaft 31 of a motor 32. The motor shaft 31 is at the same inclination as the main shaft 19, and its pinion 30 is oi. sufiicientlength to permit the gearwhee :29 to shift with the longitudinal movements of the main shaft while still maintaining: engagement.

Mounted in hearings on the under faces of the beams and rails on each side .at each end above the tank are four short shaft-s 33, 34 35 and 36 eachcarryingspur gearwheel 37 adjacent the beam. and a double sprocket wheel-38 adjacent the rail. The gearwheels 3'? are in mesh with similar gearwheels 39 on "the shafts 26 and 2?. Que the sh ort shafts, marked 33 extendsbeyond cits beam 12 and is equipped with a mitre gearwheel 40 adapted to mesh with the mitre pinion'24 fibOVG IHQIItlOHQd. Each. of the short shafts 33 and 34 carries a pulley 41.

I The mitre pinions 23 and 24 are each 10- cate'dbeyond its mitre gearwheel 25 or 40 and by shiftingthe shaft 19 either mitre pinion may be engaged with its mitre gearwheel, or both may revolve idly out of mes 1 This arrangement permitsthe mechanism to be driven either through the shaft 27 at one end or the short shaftl33 at the other and always in the same direction. I The skein carriers are preferably thin slats 42 of wood, each of a len th somewhat less than the interior width 0! the tank, and having 'a width or depth consi rably greater than the thickness. The upper and lower margins of the faces are beveled on curves, asin Figures 3, 5 and {5. to produce bluntly sharpened edges 48, and at the ends 'near'the upper edge are hollow extensions or trunnio'ns '44 adapted to lie upon the upper faces of the side walls ot-the tank and support the skeins suspended in the dye liquor or upon the rails 14 and 15.

A pair of long flexible endless belts composed of links 45 hinged each to the next at 46 run over the double sprocket wheels -38 above, and under similar sprocket wheels 47 and 68 mounted beneath the bars 17 and 18 at each end of and immediately above the tank. Between each slat 42 and the next succeeding, the pintles "for the link hinges are short studs 48 inclosed by the hinge .members and projecting on each side of the belt, and the trunnions 44 are separably joined to the linkhinges by pins 49 extending like the studs 48 through the hinge members with their reduced inner ends 50 received in the axial cavities in the ends of the trunnions as shown in Figure 5. An annular groove 51 on the reduced portion receives the nose 52 of a spring-catch mounted on the trunnion and'holds the pin 49 against withdrawal until the nose is lifted. The studs 48 and trunnions 44. 49 engage with the teeth on the double sprocket wheels, and

the links of the belt lie between the toothed members of such wheels.

The construction oi, each belt is such that the links thereof are capable of expanding and collapsing, that is they may fold so as to be disposed substantially parallel with each other. as seen in their position when the skeins are in the tank in Figure l. and then they stretch out or QXPillVi so as to ex.- tend in line with each other. like the links of an oruinaiy chain. when passing:- upward from one end of the tank. across the rails above the tank and then downwardly at the entrance end. when they autmnatically fold or cells: by their own weight.

The carriers extend transversely from one 'beltto the other and the trunnions thereon with the studs 48 are so spaced as to match to the spaces between the teeth of the sprocket wheels, and the paths of the belts lie in lines outside the tank. Four links with their studs lie between each pair of carriers on each side and the slack of the belts is such that the carriers may be planed close together across the tank with the links depending idly in loops on each side. as in Figure 1, or similarly accumulated on the rails l4 15 above as will he understood. and a suflicient number of succeeding carriers are left unloaded during the dyeing operation to permit all the loaded carriers to be thus grouped while the unloaded carriers lie distributed idly along: the paths ol' the belts. the latter being sutliciently lOIlfIOI than such paths to ali'ord the required slack.

The belts more in the direction indicated by the arrows in Figure 1. To the upward movement oi the carriers from the tank to the sprocket wheels 47 and thence to the sprocket wheels 38 provisions are made for wringing; or removing the dye liquor from the skeins; this portion oi the apparatus consists of a roller 54 mounted in brackets 55 projecting; downwardly from theruils I "1' and 15 and driven by a belt 5 from a pulley 5? on the she-lit 35, in conjunctimi with a similar roller 58 mounted in a swinging; frame 5%) fulcrumed in brackets 60 on the bars 17. and arranged tobc swung by a cam 61. operated by the hand lever 62 by which vtueroller 58 is brought into wringing contactwith the relatively fixed roller The beveled edges 43 oi the carriers perm t their easy entrance to and egress from the rollers. and the skeins hung thereon will be squeezed in their upward passage as will be understood. The size of the pulley 57 and the pulley on the roller shaft are so proi mrtiunml to revolve the rollers It a rate slightly faster than that of the carriers 42 and their skeins so that the latter will not be subjected to pulling strains in the wringing opcratimi.

At the opposite end oiithe machine is :1 device for turning the carriers successively on the trunnions 44 to change the positions arness of the skeins car ied thereon to a new point of suspension in the several skein-loops and thus insure uniform treatment throughout. The mechanism shown consists of a fixed channel 68 having a series of equally spaced transversepins' 64; adapted to engage the teeth of a star wheel 65 fixed on the trunnion 4.4- at one end of each carrier and cause the carrier to make a little more than a h revolution in its descent from th wheels 38 at the front. The weignt is sullicient to complete the revolution and suspend the skeins by a new portion.

The pulleys ll on the short shafts 3:3 and it. carry belts 66 running on pulleys st on the shafts of the sprocket wheels 68 below thus rotating the sprocket wheels 68 and serving to push each carrier forward along the tank and thus move the whole group of carriers along the tank at each accession of a carrier.

lln operating the machine for continuous treatment the pinion 24l of the main shaft is thrown into mesh with the mitre geau wheel on the short shaft 38 by which the I sprocket wheels 38 at that end of the tank are revolved and the carriers drawn down the inclined rails 1t and 15 and fed down wardly past theturning mechanism to the sprocket wheels 68, driven as above described, and pushed along the side walls of the tank, correspondingly crowding forward any previously delivered carrier and drawlog the carriers successively from the opposite end. of the tank to make the circuit again. lln this operation the skeins of each carrier are in contact with the liquor during the slow traverse of the tank and are then quickly returned for a succeeding traverse, and all the carriers may be loaded. The excess liquor may be wrung out or not as preferred; the skeins are always within the confines of the tank and the liquor may drip freely therein and it will be observed that the skeins contact only with the carriers and the dye liquor.

A sufficient number of successive carriers may be left unloaded to permit the belts to extend idly through their paths from the egress end of the tank and along the rails 14 and 15 to the ingress end, as in the drawings, and the machine driven as above until all the loaded carriers are accumulated in the tank with their skeins suspended in the liquor. The main shaft is then shifted to. the neutral position to stop the rotation of the sprocket wheels, and the skeins subjected to the action of the liquor as long as may be desired.

By shifting the main shaft to engage the pinion 23 with the mitre ,ogearwheel 25 on the shaft 27, the sprocket wheels 38 at the egress end of the tank will be rotated and all the loaded carriers accumulated on the inclined rails ll and 15 with the unloaded carriers occupying the remainder of the belt-paths. When the apparatus is used in this manner the skeins are subjected to the action of the wringing mechanism in their ascent and are then held suspended above the tank exposed to the air in carrying out the oxidizing process. fWith the apparatus thus conditioned the tank audits contents are readily accessible.

matic requiring but little labor by the attendant, and is closely analogous to the successful hand-dyeing processes.

The belts and their studs are outside the tank in all positions and by reason of their flexibility the loaded carriers may he massed side by slde as above described, permitting the whole length of the tank to be utilised,

thus greatly increasingthe capacity of the machine, and the operation maybe rapid while permitting longimmersion. during}; the slow traverse of the carriers from one end of the tank to the other.

Modifications may be made in the details of the mechanism within wide limits without departing; from the principle of the invention or sacrificing its advantages. The structure of the belts may be varied and also the sprocket wheels and driving mechanism therefor. The wringing device and also the turning device may be omitted or their functions performed by other means than those shown and described.
